A protons path can be deflected by the presence of a magnetic field. Will the proton speed up, slow down, or continue at the same speed? Explain your answer.

A cyclotron (figure) designed to accelerate protons has an outer radius of 0.333 m. The protons are emitted nearly at rest from a source at the center and are accelerated through 572 V each time they cross the gap between the dees. The dees are between the poles of an electromagnet where the field is 0.720 T. The black, dashed, curved lines Alternating AV represent the path of the particles. -Dg After being accelerated, the particles exit here. -North pole of magnet (a) Find the cyclotron frequency for the protons in this cyclotron. 1.04e33 x rad/s (b) Find the speed at which protons exit the cyclotron. m/s (c) Find their maximum kinetic energy. ev (d) How many revolutions does a proton make in the cyclotron? revolutions (e) For what time interval does the proton accelerate? awranca Barke kay Nationallab

An electron in a television tube moves with a speed of 6.34 x 107 m/s, in a direction perpendicular to the Earth's field, which has a strength of 5.00 x 10-5 T. (a) What strength electric field must be applied perpendicular to the Earth's field to make the electron move in a straight line? kV/m (b) If this is done between plates separated by 1.05 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a correction.) V

A mass spectrometer is being used to separate common oxygen-16 from the much rarer oxygen-18, taken from a sample of old glacial ice. The ratio of the masses of these two ions is 16 to 18, and the mass of oxygen-16 is 2.66×10^−26 kg. They are both singly charged, and they both travel at 4.84×10^6 m/swhen they enter the mass spectrometer with a 1.11T magnetic field that is perpendicular to the particle velocity. What is the separation between their paths, in meters, when they hit a target after traversing a semicircle?
